## Overview

The Bosch GSA18V-083B is a lightweight, compact 18V cordless reciprocating saw engineered for professionals who demand power and precision in tight spaces. Featuring a high-speed 3,050 SPM motor, an optimized 0.83" stroke for efficient cutting of wood and metal, and a toolless blade-change system, it’s designed for fast, fatigue-free operation. Its ergonomic soft-grip handle, LED illumination, and safety lock switch make it a versatile, reliable tool for electricians, plumbers, and DIY pros alike. Battery and charger sold separately.

## Description

The Bosch GSA18V-083B 18V Reciprocating Saw is built to easily move through difficult tasks in tight spaces that other recip saws can't fit. It has the best power-to-weight ratio in its class, and delivers a fast 3,050 strokes per minute. At only 15-3/4 In. long and 4.4 Lbs. (bare tool), this powerful, compact cordless recip saw provides an impressive 0.83 In. stroke. This allows electricians or plumbers to remove more material per stroke. The tool's light weight is ideal for continuous cutting in over-the-head applications. The easy-to-operate blade-change system allows for fast toolless blade changes, and its LED light helps to illuminate the cutting zone. This tool comes with a lock-out switch, to prevent inadvertent startup of the tool, for added user security. The GSA18V-083B is a bare tool; the battery and charger are sold separately.

Review: Very easy to be safe and use effectively! - I am a Bosch fan and this tool just added more joy to my life. As a single lady I bought this as my Mothers' Day gift and included the blade assortment too. So Worth While!! I love the precision on drywall during demo. I also pack it along when I cut my own Christmas tree. I just used it this fall for tree trimming and it made the chore so much easier!. I have chainsaws for the big stuff but this works smoothly and effortlessly and is easy to control. It is perfectly sized and balanced for my smaller scale projects and my body weight and stature. Ladies! Do yourself a favor and add one of these to your own tool collection. Move out of the kitchen from your electric knife on roasts and get crafty with a marvelous tool like this one. German engineering for quality and durability. Serious Fun!
Review: Updated review - Big changes! - Yes I originally gave this tool one star. You can read my original review, below. So what's changed? Well, I now have a lot more experience with the saw, and understand that it all depends on how you plan to be using it. Bosch makes 3 different cordless recips and I have the luxury of owning all three (see attached pic). I use all three regularly, for very different purposes. The 12V is terrific for light duty trimming, landscaping, etc. - very lightweight and portable. The 18V "conventional" is hands down the best for demolition or other construction work. If you will own only one 18 / 20V max (which are both the same thing) cordless recip I feel strongly this is the one to own. However, this 18V "compact" saw is used a lot in the course of my volunteer work at state parks. I use it for trail maintenance and also for the removal of invasive and harmful species. The lighter weight and somewhat smaller size is a real advantage when walking for miles through the woods! In conclusion, this is a really great saw. Whether it's the best saw for you depends on what you need done. ORIGINAL REVIEW Yeah, I am a Bosch fan. So why 1 star? It's because you definitely don't need this. If you are doing real demolition work, get the "regular " saw, it's a lot better. If you need smaller, are space confined, get the 12v version. It is better for that job. This saw is not bad tool, in fact far from it. The cutting speed and power are everything I had expected. However, its size and weight were definitely not. It fills a tiny niche, at best.
